Hi guys, i have a problem with LTSP (currently using 5.4.4). When login on local LTSP server with LDM, it works fine. Now, when login to another server using LDM (by using SERVER = otherServerIp) it still logins in the local server. So, just in case changed to xdmcp to login to another server, and black screen appears intead of login. the xdcmp in the other server is enabled and works.

I'm desparetly short on sleep and in need of basic help with LTSP5. Had an LTSP4 server that I installed years ago and it 'just worked' -- until it crashed. Decided to upgrade everything to fresh and import the data but have been struggling to get it back up. Finally got *some* clients to boot but other are failing with a kernel panic. Also fighting permissions and the proper way to make existing home directories available to the c

19:28

<alkisg>

Distro/version? Also your sentence was too big and it was truncated by irc

19:28

<milledel>

Base system is Debian, xfce for the Desktop with lightdm.

19:28

Debian 7 that is.

19:29

Sorry about the rambling.

19:30

<alkisg>

The chroot is wheezy too, right? What kernel panic, and in which stage?

19:31

<milledel>

Yes, chroot is wheezy as well. Main server is AMD64 but clients are i386.

19:32

<alkisg>

!quiet

19:32

<ltsp`>

quiet: to enable the Debian kernel and initramfs to show up more messages, in order to better troubleshoot the boot process, remove "quiet" from /var/lib/tftpboot/ltsp/i386/lts.conf

19:32

<alkisg>

Do that, and then write the last things you see before the kernel panic, and a few lines of the kernel panic (or screenshot)

It stops at .../init-lstp.d/50-rm-system-service with 'arithmatic expression: expecting primary'

!learn quiet as to enable the Debian kernel and initramfs to show up more messages, in order to better troubleshoot the boot process, remove "quiet" from /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

19:42

<ltsp`>

The operation succeeded.

19:43

<milledel>

OK, done. rebooting now...

19:47

Drops me to a shell... last few lines are: modprobe: modules overlayfs not found in modules.dep

19:47

followed by: aufs: module is from the staging directory, the quality is unknown, you have been warned.

19:48

then cannot set terminal process group (-1): Inappropriate ioctl for device.

dmesg again points out that the aufs module is of unknown quality but give no other insight. Syslog does not exist.

20:07

which is strange... it used to be there...

20:08

<alkisg>

Ah it's too early for syslog, ignore that one

20:08

Do another try: break=bottom

20:08

(not ltsp.break this time)

20:08

and at that breakpoint, ls /proc

20:09

<milledel>

I'm with you... I never syslog before 9:00PM.

20:09

Will do, hang on.

20:12

break=bottom -> ls /proc shows proc to be populated.

20:14

<alkisg>

So it's not migrated in the real root later on...

20:16

milledel: at that point, is there a /root/run dir on the client?

20:18

/proc is supposedly moved to the real file system by <chroot>/usr/share/initramfs-tools/init:

20:18

mount -n -o move /proc ${rootmnt}/proc

20:18

<milledel>

Yes, /root/run exists.

20:20

<alkisg>

It sounds like a bigger initramfs problem then, you could try installing wheezy locally on one of those clients to verify it's affected even without ltsp, and then file a bug report in initramfs-tools etc etc

<milledel>

My guess it that is an install/config problem on the server side -- these client were booting mere hours ago with the same client build. What changed was that I was working to get Home dirs mounted/migrated.

20:23

<alkisg>

Is <chroot>/run on the server a directory or a symlink?

20:23

<milledel>

Directory.

20:24

<alkisg>

On the client, while still on the "break=bottom" break point, try this:
